What can I pack in my "checked" baggage? Most airlines allow you to carry up to two litres of personal care aerosols in your checked baggage but note that different airlines (and check-in staff!) may interpret the policy differently, so make sure you check your airline's website before you pack.
Does TSA allow aerosol cans?
You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes in your carry-on bag and through the checkpoint. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item.
Can I put toiletries in hold luggage?
The main rule to remember is that you must not take any more than 100ml of a restricted liquid into the cabin of a plane, and those liquids should be placed into individual 100ml containers. Any liquid that you need more than 100ml of should be packed in your hold luggage. “Liquids” include: Drinks.
